I've committed a similar fixed to head after talking it over a bit with
Simon.  We probably would be checking for success on mounting devfs and
failed the jail entirely if it doesn't happen, but that's a bigger step
and from your description it appears to me that might cause problems in
some scenarios.

P.S. rc.d/jail fixes are the sort of thing that will often need active
followup when assigned to freebsd-rc.  There's a note at the top that
most of us take to mean "don't touch this file without so approval"
which is a moderate psychological barrier to handling these PRs.
